The two were filmed in a dressing room shaking and screaming when the announcement was made a few hours before the live telecast. "'Bad Blood' just won a Grammy for Best Music Video and we are not ok. @selenagomez," she wrote on Twitter.
"I got to be in my best friends [sic] first Grammy award winning music video!!!!!!?! #Grammy9 @taylorswift13," Selena retweeted.
